When To Take Melatonin
It is essential to take melatonin at the correct time of day. Taking it too early or too late can alter a persons biological clock and shift their sleep and wake times.
The National Health Service recommend taking melatonin 12 hours before your desired bedtime which for most is around 8:00-9:00 pm.
People who are traveling and want to take melatonin to prevent jet lag should start taking this supplement a few days before they leave. This will help acclimatize their bodies to the new time zone. It is best to take melatonin 2 hours before bedtime at the destination.
A person may recover more quickly from jet lag if they take melatonin.
Taking melatonin may help with a few different health conditions, including:
- jet lag
- delayed sleep-wake phase disorder
- sleep problems in children with attention-deficit hyperactivity disorder and autism
- anxiety before and after surgery
One report suggests that melatonin may also provide the following benefits by:
- protecting the heart by reducing blood pressure in people with insomnia
- having protective effects against cancer and enhancing the impact of cancer treatments
- reducing the damaging effects of obesity on the body by lowering inflammation
- slowing mental decline in people with dementia
However, more research will be necessary to prove these benefits in clinical trials.
Melatonin: Natural Or Synthetic
One would assume that melatonin is melatonin, but that is clearly not the case.
Two forms of melatonin exist in the general market. One is the natural form which comes from the pineal gland of animals. It can be mixed with unknown synthetic material or unknown synthetic material free from animal tissues. Life Choice® Melapure® Melatonin uses a patented synthetic form following the same chemical pathway as natural melatonin; it is USP pharmaceutical grade and protected by a drug manufacturing file. Being a USP grade ofsynthetic melatonin, it is safer to use because it is free from biological contaminants. Natural sourced melatonin, on the other hand, may pose a risk to humans because it can be contaminated with animal viruses.
As a background, there are 3 grades for raw material: pharmaceutical ; food grade, which meets the standards for human consumption and without quality testing oversite; and feed grade, which meets the standards for animal consumption and less quality testing oversite. The lower grades are mixed with fillers, etc. and the amount put in the capsule will be more likely to vary , while the USP standard must be pure and exactthis makes all the difference in what peoples experience with melatonin will be.

Regulation Of Bone Metabolism
Studies in mice suggest that the pineal-derived melatonin regulates new bone deposition. Pineal-derived melatonin mediates its action on the bone cells through MT2 receptors. This pathway could be a potential new target for osteoporosis treatment as the study shows the curative effect of oral melatonin treatment in a postmenopausal osteoporosis mouse model.

Side Effects Of Melatonin
Melatonin is considered relatively safe for short-term use and has few risks. However, some children who take melatonin supplements may experience mild symptoms. These symptoms may include bedwetting, drowsiness, headaches, and agitation.
Currently, there is little research on the long-term effects of melatonin use in children. Some experts question if melatonin, because it is a hormone, can affect other hormonal development in adolescents. Further research must be conducted to more clearly understand the long-term effects of melatonin on children.
How Can I Boost Melatonin
By far the best way to boost melatonin production is to increase your exposure of natural sunlight during the day time and reduce light levels in the evening . If you supply the body with the right environment, reducing light and exposure to blue screens after 4 pm, the natural stimulation will ensure ample supply, says Lola Biggs, dietitian at Together Health.;
You can also help to boost melatonin by adding certain foods into your diet. Tart cherries in season are my favourite tasty source of food-based melatonin, says Lola. Research shows that they can have above average concentrations of melatonin and are high in antioxidants. Eggs are one of the best sources of melatonin as well as being full of essential nutrients. Bananas and nuts such as almonds and walnuts are also rich in melatonin and are the perfect night time snack to promote natural circulation of this helpful bedtime hormone.;
“In addition, help may be found in providing the right nutritional building blocks, foods rich in amino acid tryptophan offer a long term sustained improvement in circadian rhythms involved in our sleep-wake cycle.”

Why Melatonin Is Bad For You
If its all natural, why is melatonin;bad for you? my mom asked, when I expressed my concern with this supplement after learning that she takes it on-and-off for her insomnia. Boy, have I got a blog post for you! I replied.
In short, melatonin is a hormone that correlates with sleep cycles and plays beneficial roles in numerous physiological functions. But melatonin supplements are;neither a safe, natural nor effective solution to insomnia.
Jet Lag And Shift Work
Melatonin is known to reduce jet lag, especially in eastward travel. If the time it is taken is not correct, however, it can instead delay adaptation.
Melatonin appears to have limited use against the sleep problems of people who work shift work. Tentative evidence suggests that it increases the length of time people are able to sleep.
What Happens If I Have Too Much Melatonin
There are large variations in the amount of melatonin produced by individuals and these are not associated with any health problems.;The main consequences of swallowing large amounts of melatonin are drowsiness and reduced core body temperature. Very large doses have effects on the performance of the human reproductive system. There is also evidence that very high concentrations of melatonin have an antioxidant effect, although the purpose of this has not yet been established.
What Are The Health Benefits Of Taking Melatonin
Melatonin supplements may help with certain conditions, such as jet lag, delayed sleep-wake phase disorder, some sleep disorders in children, and anxiety before and after surgery.
Jet lag affects people when they travel by air across multiple time zones. With jet lag, you may not feel well overall and you may have disturbed sleep, daytime tiredness, impaired functioning, and digestive problems.
Research suggests that melatonin supplements may help with jet lag. This is based on medium-sized reviews from 2010 and 2014.
- Four studies that included a total of 142 travelers showed that melatonin may be better than a placebo in reducing overall symptoms of jet lag after eastward flights. Another study of 234 travelers on eastward flights looked at only sleep quality and found low-quality evidence that melatonin may be better than placebo for improving sleep quality.
- Two studies that included a total of 90 travelers showed that melatonin may be better than a placebo in reducing symptoms of jet lag after westward flights.
Delayed sleep-wake phase disorder
People with DSWPD have trouble falling asleep at the usual times and waking up in the morning. They typically have difficulty getting to sleep before 2 to 6 a.m. and would prefer to wake up between 10 a.m. and 1 p.m.
Some sleep disorders in children
Because of these uncertainties, itâs best to work with a health care provider if youâre considering giving a child melatonin for sleep problems.

Effect Of Melatonin On Gene Expression
The presenting results on the melatonin genomic effect is rather few. In a study of cytogenecity, it was found that a decrease in the gene activity of ribosomes as a result of a pinealectomy in rats . Menendez-Pelaez et;al. declared that melatonin treatment reduces mRNA level in the synthesis porphyrin, and 5- aminolevulinate synthase, in the Syrian hamsters Harderian glands. Melatonin declines mRNA levels of histone H4 and stopped age-attributed mRNA Bcl-2 reduction, in mice thymocytes . Also, melatonin elevated some antioxidant enzymes mRNA in Syrian hamsters Harderian gland . Supplementation of melatonin produced significant enhancement in relative levels of mRNA for Mn-SOD, Cu,Zn-SOD and glutathione peroxidase in cerebral cortexes of rat . Melatonin markedly modulates the mRNA of gonadotropin-releasing hormone. It was observed that melatonin regulate transforming growth factor- gene expression level, macrophage-colony stimulating factor , tumor necrosis factor- mice .
Does Melatonin Have Any Side Effects
A few studies have investigated the safety of melatonin, but none have revealed any serious side effects. It also doesnt seem to cause any dependence or withdrawal symptoms .
Nonetheless, some medical practitioners are concerned that it may reduce the natural production of melatonin in the body, but short-term studies suggest no such effects .
Several studies have reported general symptoms, including dizziness, headache, nausea or agitation. However, these were equally common in the treatment and placebo groups and couldnt be attributed to melatonin .
Melatonin supplements are generally considered safe in the short-term, even when taken in very high doses. However, more research on its long-term safety is needed, especially in children .
A few mild side effects and drug interactions are discussed in the chapters below.
Summary Melatonin supplements are considered safe, and no studies have revealed any serious side effects to date. Yet, more research is needed to evaluate its long-term effects.

Melatonin For Sleep: Does It Work
Melatonin sleep aids are growing in popularity, with 3 million Americansusing them in 2012, according to a nationwide survey from the Centers forDisease Control and Prevention. If youre among them or are consideringmelatonin for sleep, its smart to understand exactly how melatonin works.;
Your body produces melatonin naturally. It doesnt make you sleep, but as melatonin levels rise in the evening it puts you into a state of quiet wakefulness that helps promote sleep, explains Johns Hopkins sleep expert;Luis F. Buenaver, Ph.D., C.B.S.M.
Most peoples bodies produce enough melatonin for sleep on their own. However, there are steps you can take to make the most of your natural melatonin production, or you can try a supplement on a short-term basis if youre experiencing insomnia, want to overcome jet lag, or are a night owl who needs to get to bed earlier and wake up earlier, such as for work or school.
If youd like to harness melatonins sleep-inducing effects, Buenaver recommends taking these steps.
The Dark Side Of Melatonin
Twenty-one years ago, MIT neuroscientist Dr. Richard Wurtman introduced melatonin as a new solution to sleep problems. His lab patented supplements in hopes of curing insomnia in the older population, whose melatonin receptors calcify with age.
Researchers say pills of the natural hormone…will bring on slumber quickly without the addictive effects of drugs, the New York Times reported at the time. In the same article, Judith Vaitukaitis, then director of the National Center for Research Resource, said the hormone offered hope for a natural, non-addictive agent that could improve sleep for millions of Americans.”
Wurtman himself wasnt quite so cavalier. In that same article, he warned, People should not self-medicate with melatonin.
Nonetheless, melatonin was a hit. In the last two decades, the all-natural sleep aid has earned a spot in medicine cabinets across the country. Inexpensive, easily accessible, naturally occurring and considered safe, melatonin appeals to the those whod rather avoid prescribed pills. Naturopaths, chronic insomniacs, shift-workers and frequent fliers pop milligrams of melatonin without thinking twice.
According to the National Center for Complementary and Integrative Health, nearly 1.3 million American adults reported taking melatonin in February, 2015. Parents are even handing it out to their kids 419,000 as of February believing melatonin to be a harmless, naturally produced hormone.

How To Take Melatonin Safely
A low dose of melatonin is considered .5 milligrams to one milligram, which Avidan says can be enough to adjust somebody’s circadian pattern in the case of situations like jet lag or daylight savings.
If someone is really struggling to fall asleep, they might need to move up to a three milligram dose, which can be considered the “hypnotic dose.”;
Certain conditions may call for even higher doses. “High doses between five to 15 milligrams are available for people who have a certain parasomnia an abnormal behavioral activity that occurs during sleep, for example, sleepwalking,” Avidan says.
However, a dose of five milligrams or more should not be taken without approval from your doctor.;
As far as when you should be taking it, be sure to take a melatonin supplement about two hours before your desired bedtime. Since melatonin affects circadian rhythms, it is important to avoid taking it too late at night.
For example, taking melatonin at 3am after tossing and turning could throw off your sleep schedule and affect your rest for the remainder of the week.;
Quick tip: Remember that melatonin is most effective when combined with a regular bedtime schedule and good sleep hygiene.;
“It is impossible to overdose on melatonin since toxic levels of melatonin have never been registered,” says Lorenzo Franceschetti M.D., a researcher at the University of Milan, who has conducted extensive studies on melatonin.

Is It A Hormone
Melatonin is a hormone. The pineal gland in the brain releases it in cycles. Production increases at night when the light outside starts to fade.
Melatonin acts as a chemical messenger. It tells other organs and tissues how to function. Melatonin signals to the body that it is time to go to sleep.
Melatonin is known as the sleep hormone. People with low melatonin levels may not sleep as well as those who have higher levels.

Can Promote Eye Health
Melatonin is high in antioxidants that can help prevent cell damage and keep your eyes healthy.
In fact, research suggests that melatonin could be beneficial in treating conditions like glaucoma and age-related macular degeneration .
In a study in 100 people with AMD, supplementing with 3 mg of melatonin for 624 months helped protect the retina, delay age-related damage and preserve visual clarity .
Additionally, a rat study found that melatonin decreased the severity and incidence of retinopathy an eye disease that affects the retina and can result in vision loss .
However, research is limited and additional human studies are needed to determine the effects of long-term melatonin supplements on eye health.
Melatonin is high in antioxidants and has been shown to treat eye conditions like age-related macular degeneration and retinopathy in human and animal studies.
Melatonin has been shown to block the secretion of stomach acids. It also decreases the production of nitric oxide, a compound that relaxes your lower esophageal sphincter, allowing stomach acid to enter your esophagus .
For this reason, some research suggests that melatonin may be used to treat heartburn and GERD.
One study in 36 people showed that taking melatonin alone or with omeprazole a common GERD medication was effective at relieving heartburn and discomfort .
How Melatonin Works In The Brain
The pineal gland acts as the third eye to release melatonin.
The pineal gland and melatonin are the bodys internal visual system. As the third eye, the pineal gland contains visual cells. These detect signals from the eye, via the hypothalamus. They are like the rod and cone cells of the eye.
During daytime, light detected in the eyes, signal to the hypothalamus and relay to the pineal gland. Light decreases the amount of serotonin converted to melatonin in the pineal gland.
In the darkness, serotonin converts to melatonin. It begins a rhythm to release melatonin to the bloodstream. After the sun sets, melatonin production begins, and after four hours of darkness, melatonin levels reach their peak. It lines up with the time to sleep.
As melatonin is released from the pineal gland, it feeds back to the suprachiasmatic nucleus in the hypothalamus. It entrains the circadian rhythm that signals the brain to sleep. There are melatonin receptors in the SCN that allow the SCN to detect melatonin.

Melatonin And Children With Adhd
As many as 70% of children with ADHD experience sleep problems. They frequently experience excessive daytime sleepiness caused by initial insomnia, or difficulty falling asleep at night.
Studies show that children with ADHD who take melatonin experience improved sleep. One study found a reduction in insomnia, leading to children falling asleep an average of 16 minutes earlier.

What Are The Side Effects Of Melatonin
Short-term use of melatonin has relatively few side effects and is well-tolerated by the majority of people who take it. The most commonly reported side effects; are daytime drowsiness, headaches, and dizziness, but these are experienced by only a small percentage of people who take melatonin.
In children, the reported side effects of short-term use are similar as in adults. Some children may experience agitation or an increased risk of bedwetting when using melatonin.
For both children and adults, talking with a doctor before taking melatonin can help prevent possible allergic reactions or harmful interactions with other medications. People taking anti-epilepsy and blood thinning medications, in particular, should ask their physician about potential drug interactions.
The American Academy of Sleep Medicine recommends against melatonin use in people with dementia, and there is little research about its safety in women who are pregnant or breastfeeding.
There is also very little data about the long-term effects of melatonin supplements in children or adults. There is some concern that sustained use of melatonin could affect the onset of puberty in children, but research so far is inconclusive. Because the long-term effects are unknown, people should maintain an ongoing conversation with their doctor about using melatonin and the quality of their sleep and overall health.
